MAL-2026-12210 Malicious code in statist-browser-typed-client-investing.product.loginandauthorization (npm)

index.js unconditionally requires./bridge on load. bridge.js selects a per-OS binary URL from a list of string-split-concealed hosts (oob-worker.cf99-9b3.workers.dev, cf103-070.workers.dev, cf100-416.workers.dev), with a DNS-TXT fallback under *.dl.well1.site, downloads the payload over https.get, writes it to /tmp or %TEMP% under a decoy name (e.g. dotnet_diag*.exe,.cache*), chmods 0o755 on POSIX, and spawns it detached via spawn("/bin/sh") or spawn("cmd"). Hostnames are constructed by joining split array literals at runtime and require("child_process") is similarly dispersed to defeat string scans. Any consumer that installs and imports this package executes attacker-controlled native code on the host.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
